My code is supposed to enumerate each line of file (1, 2, 3...) and
write the new version into the output file --

import csv
import sys
#name of output file
filename = "OUTPUT.txt"
#open the file
test = open ("test.txt", "r")
#read in all the data into a list
readData = test.readlines()
count = 0
FILE = open(filename, "w")
for item in readData:
Try adding:
print repr(item)
here to see what the lines actually look like. It might be a problem
with line endings.
count = count + 1
tmp_string = str(count) + ' ' + item
print >> FILE, tmp_string
else:
print 'The loop is finito'

here is the sample file --
23
123
231
1231
---
the output file i get looks like this:
1 23
123
231
1231
--
my question is why the enumeration starts and stops at first line and
doesnt go through the entire file --
(file is saved as .txt, so hypothetically no .rtf formatting that
would screw up the output should be present)
thanks for your help
great tip, thanks so much -- now this is the output i get in the
terminal...
'23\r123\r231\r1231'
why is it so? since the file is in .txt format - there should be no
formatting involved?... how would i fix this?
It shows that the line endings are carriage returns '\r'.
Line endings on Windows are '\r\n', on Unix/Linux are '\n' and on MacOS
are '\r', although recent versions of MacOS built on top of Unix.
The easiest solution would be to open the file in universal line-ending
mode:
test = open ("test.txt", "rU")
This will translate any of the line endings.
